Claims. (Cl. 198-30) This invention relates to improvements in a device for orienting articles which are conveyed forwardly to a packaging machine and is a division of our copending application Serial No. 194,166, filed November 4, 1950, Patent2,744,609, issued May 8, 1956, for Apparatus for Separating and Feeding Articles.

in the packaging of articles where a plurality of articles are adapted to be disposed in a single package in a predetermined orderly manner it is frequently desirable to feed the articles to such packaging machine in seriatirn and package them in multiple units. In the patent above mentioned an apparatus is described for changing the flow of articles to be packaged from a seriatim flow to a parallel flow. To accomplish this end a plurality of electric eye trigger mechanisms are described, said mechanisms comprising a plurality of sets of photoelectric celllight source pairs disposed parallel to the series flow of the articles, each cell, through a described electric circuit, energizing a solenoid-operated air jet'which blows the articles from their series conveyor to a transversely moving conveyor when the articles interrupt the light beam associated with an energized photoelectric cell.

Many articles packaged in accordance with the teachings of said above mentioned'patent require reorienting when the articles are discharged to the transversely moving conveyor and hence as an important feature of the present invention means is contemplated for orienting or di'rectionalizing' the articles after their diversion or segregation from series fiow to parallel flow.

In one commercial packaging operation, the articles packaged are of generally parallelepiped shape, that is, they are in length greater than their thickness or width. In packaging the articles, they are all disposed in the package with their long axes parallel. In diverting such articles from series flow or travel to parallel flow or travel, it frequently happens that the articles become misaligned as they are carried to the packaging machine whereas it is essential when acted on by the packaging machine that they be disposed with their long axes parallel. The present invention contemplates means for orienting those articles in their passage forwardly, after diversion from series travel, whereby, they are carried forwardly with their long axes parallel to each other and parallel to their direction of travel. 7

The present invention is particularly adaptable to the handling of shredded wheat biscuits in their passage to a packaging machine and will be herein described, for purposes of illustration, as handling such articles. However, it is to be understood that the invention is not to be limited to the handling of shredded wheat biscuits, since it wiil find use in the handling or" other articles and in other environments.

As has been hereinbefore described, the present machine contemplates being used with a preconveyor or series conveyor such as described in application for United 2 carries shredded wheat biscuits 3 upon its upper pass, the

biscuits 3 being moved by the conveyor in seriatim, one biscuit following the other in the direction of their longitudinal axis. If desired the conveyor comprising the belt 2 may be driven by a sprocket chain 4 trained around sprocket wheel 5 carried upon shaft 6, the same shaft which carries the conveyor roll 1. The sprocket chain 4 may also be trained around sprocket wheel 7 mounted upon the end of shaft 8 which, in turn, may be journaled in bearings 9 and it? carried by a U-shaped frame member 11. The frame member 11 may be supported by a suitable standard 12 comprising a portion of the frame of the machine.

The shaft 8, if the present machine is used with a packaging machine, may be driven in timed relationship with the mechanism of the packaging machine and hence by the provision of sprocket chain 4 the preconveyor or series conveyor may be driven in timed relationship with the packaging machine.

A drum 12 is also mounted upon shaft 8 between bearings 9 and 19. A conveyor belt 13 may be trained around drum 12 at one end of its travel. The conveyor belt 13 is also trained around drum 14 '(Fig. 3), said latter drum being mounted upon shaft 15 journaled in the adjustable bearing block 16, said block being slidably positioned in guides 17 whereby the conveyor belt 13 may be appropriately tightened by the manipulation of screw 18 carried by frame member 19. The conveyor belt 13 preferably comprises a relatively thin resilient metal belt such as a stainless steel belt. travels in a direction transversely to the length of the machine proper.

A ramp 19 is disposed between roll 1 and drum 12 and functions to support the biscuits 3 delivered from the conveyor belt 2 to the conveyor belt 13. An arm 20 is loosely positioned upon shaft 8, said arm carrying a pin 21 at its end upon which a sprocket wheel 22 is mounted for free rotation. A sprocket chain 23 is trained around sprocket wheel 22 and at the opposite portion of its travel is trained around a sprocket wheel 24 carried by shaft 25 which, in turn, is journaled in bearing 26. The bearing 26 is carried by bracket 27 which is secured to the U-shaped frame 11 by means of screws or the like 28. A roll 29 is carried upon shaft 25, said roll being preferably constructed of relatively The conveyor belt 13' soft sponge rubber'whi'ch maybe provided with radial cuts or slits 30 at its periphery to render the periphery thereof extremely soft and yielding.

. Theroll ,29 is positioned above the drum 12 and its.

periphery is so spaced from said drum that the surface of .the roll exerts ,a relatively mild frictional pressure upon the upper surfaces'of the biscuits 3 movingalong ramp 19 between conveyor belts 2 and 13; As is :well known such-.biscuits are relatively fragile and, hence, the rollpressuremust, of necessitybe-mild. This is also true with regard'to the remaining elements of the machine which handle the biscuits, that is, they are treated gently. In operation, the peripheral speed of roll 29 is the same as the translatory speed of the belt 13 and substantially faster than the translatory speed of belt 2 whereby the biscuits 3 transferred from the ramp 48 with no driving stress being exerted by the conveyor.

19 to the belt 13 are spaced endwi'se from each other.

The ramp 19 is inclined downwardly from'the belt 2 to the belt-13 whereby the biscuits 3 delivered by .the belt 2 move by gravity beneath roll 29 whereupon they are transferred to the upper pass of the belt 13.

The arm 20 which carriespin 21 also carriesan arcu ate extension 3l' which is provided, adjacent its end,

'Wlth a slot 32. An adjusting screw 33 is carried by frame 11, the arrangement being such, that arm .20 may be rotated about shaft 8 to properly tighten the sprocket chain 23 which drives melon 29. 1

Referring particularly-to Figs. 1, 2 and 3 themachine comprises.oppositelongitudinal frame members 34-34 extending forwardly from'the conveyor belt 13. Bearings- 35"35 are carried by opposite frame-members 34 and a shaft 36 is journaled in 'said bearings. A standard 37 is positioned adjacent one end of shaft 36, said standard supporting a bearing- 38 in which shaft 39 is journaled; A coupling 40 connects shafts. 36 and 39.,

At the opposite end of shaft 39 a bevel gear 41 is positioned, said gear meshing with 'a companion bevel gear 42 mounted upon shaft 43. spur gear 44 is also j mounted upon shaft 43 and meshes with a spur gear 45 mounted upon shaft '8. As 'will be hereinafterfmore fully described ,shaft 36 functions to drive'shaft 39 which in turn through thefmechanism hereinbefore. described functions to move conveyor 13.

I A roll 46 is carried upon shaft 36 and a relatively wide flexible conveyor 47 is trained around roll 46. The

flexible conveyor 47 is also trained around a roll 48 carried upon shaft 49 which, in turn, is journaled in bearings 50 carried at the forward end of beams 34-+34.

Angle irons. 51-51 are positi'oned-luponeach of the beams 3434, said angle irons supporting opposite guides 52 in each pair; of which a bearing block '53 is sslidably'positione'd. At the lower ends of each p air of' guides 52 an angle iron 54 is employed as a spacer. A shaft 55 is journaled in the opposite-bearing blocks 53 and, the flexible conveyor 47 is trained around a roll- 56 carried by shaft 55. .A screw 57 is 'operatively posi- V opposite ends to the respective blocks 78. At their for-';

tioned in each of the angle irons 51, the ends of said screws being .pivotally connected to the bearing blocks 53; Lock nuts 58 are threadedly engaged upon the ends 7 of'screws 57 whereby the hearing blocks 53 maybe ad justably positioned vertically within guides52to adjustably tighten the flexible conveyor .47.

An electricr motor 59' is positioned beneath the frame 1 me'mhers3434 and functions'to drive shaft 49. 'iA; sprocket wheel 60 is positioned upon the shaft of the motor'59and .a sprocket Wheel 61 is positioned upon the end of shaft 49,-a sprocket chain 62 being trained around the sprocket wheels 60 and 61. A pair-of sprocket wheels 6363 arecarried' at opposite ends of shaft 49 V and similarly a pair of sprocket wheels 64-64 arelcarried upon shaft 36. Sprocket chains 65 65 are trained around each pair of sprocket wheels..63- 64. in this fashion shaftsl49' and 36 are driven'shafts whereby the conveyor 47 is-merely carried upon-the rolls 46 and A plate 66 is positioned beneath the upper pass of the flexible conveyor 47, said plate being supported by angle irons 67 which, in turn, are carried by brackets 68 mounted upon the opposite beams 34. By the provision of plate 66 the flexible conveyor 47'during its upper pass is'supported byand slides over said plate.

An angle iron '69 (Figs. 2- and 4) is secured to transverse frame member 70 and extends across the machine substantially coextensive with the roll '46. A plate 71 V is secured to the angle iron' 69 by means of screws .72

or the like and at the upper edge'of the plate 71a'ran1p- 73 is carried. The upper edge of the plate 71 is substantially -flush'with the upper pass of the conveyor belt 13 and'the ramp 73 is inclined' downwardly fromthe upper edge of said plate to a positionimmediately above the upper pass of. the flexible conveyor 47.

A plurality of parallel partitions 74 ,are secured to j the ramp 73 and divide said ramp into a plurality of passageways 75 (Fig. 7). Each-passageway 74 is covered by a cover 75', each of which carries at its end 1 a relatively resilient blade or leaf spring 750:. A partition plate 76 is secured to each partition 74, said partition plates being positioned immediately. above the upper pass of the flexible conveyor 47 and in effect constituting continuations of the partitions 74 whereby a plurality, of passageways 77 are provided above the conveyor which, in effect, constitute continuations of the passageways 75. V a V A pair of supporting blocks 78--78 are positioned upon the upper portions of the opposite frame members or beams 3434 and an angle iron 79 is secured at its ward edge, the. partition plates 76 are secured to the lower portion of the angle iron 79 and are supported thereby and ma intained "in desired spaced relationship 7 with respect to each other.

The partiti0ns74 upon the ramp 73'are disposed'par allel to each'otherfand substantially parallel to the direction of travel of the upper 'pass of the conveyor 47; The partition plates 76, however, comprising continuations.

of the partitions 74 are disposed in a diagonal fashion 'with respect to the directionof travel of the upper'pass of the conveyor 47. Adjacent the angle iron-79 the partition plates 76 are bent to extend for a relatively 'short' distance parallel to the direction of travel of the screen conveyor '47. The purpose of this arrangement willbe hereinafter more fully described.

A frame structure comprising upright frame mem-' bers 80 and 81 embraced by cross members 82 and 83 is positioned adjacent the charging end of the machine, the 1 'frame membersextending above the upper pass of the conveyor belt 13. The frame'members 83 extend beyond the upright frame members 81 respectively on each side of themachineto provide supporting arms 84; Brackets 85 are mounted upon the arms 84-and are adapted to be secured to angle irons 86. A bolt 87 passes through each of the angle irons 86 and secures each such angle iron to a bracket 85, the arrangement being such thatthe angle irons 86 are adjustable to a desired angularly inclined position with" respect to the brackets 85..

At the lower endsof the opposite angle irons 86a .transverse angle member88 is secured, the transverse angle member 88 being adapted to su of spaced electric eye assemblies 89. 1

Each electric eye assembly 89 comprises a channel member 90 having end flanges 91 and 92. Each channelmember 90 issecured to 'a diagonally positioned plate 93 which may be secured to the angle member 89,

preferably by welding. A screw94 functions to secure The end the channel members 90 to the plates 93.

V flange 92'carried by each channel member 90 carries a a bracket 95 which is secured to .the flange 92 by screws 96, the bracket 95 in turn supporting a photoelectric cell port a plurality.

97. Each end flange 91 carried by each channel member 90 carries a bracket 93 which is secured to each flange 91 by screws 99. A light housing 100 is carried by each of the brackets 98.

There are the same number of electric eye assemblies 89 as there are passageways 75 plus one additional assembly 101 (Fig. 3), the unction of which will be hereinafter more fully described. The assembly 101 is identical with the assemblies 89 but is used for a difierent purpose. The arrangement is such that each illuminating device 100 casts a beam toward the active portion of each corresponding photoelectric cell 97 and the assemblies are so oriented with respect to the conveyor 13 that a biscuit 3 carried upon the surface of said conveyor will intercept the beam projected from the illuminating devices 100 when the biscuit is carried forwardly upon the conveyor.

An angle iron 102 is disposed transversely across the machine and is positioned adjacent the path of travel of the upper pass of the conveyor 13. Beneath the lower leg of the angle iron 102 a plurality of air nozzles 103 are carried, the openings of the nozzles being directed immediately above the upper pass of the conveyor 13 in such a manner that when air is discharged from the nozzles it will be projected upon a biscuit 3 carried upon the conveyor 13. A pipe 104 connects with each air nozzle 103, said pipe connecting at its opposite end into a control valve 105. Each control valve 105 connects with an inlet pipe 106 the opposite end of which is connected to a source of fluid under pressure preterably air (not shown).

There are as many air nozzles 103 as there are electric eye assemblies 89 and each air nozzle is positioned in the same vertical plane with the beam projected from the illuminating devices 100 toward the photoelectric cells 97. Ashas been hereinbefore described the number of electric eye assemblies 89 is equal to the number of passageways 75. Similarly the number of air nozzles 103 is equal to the number of passageways '75 and said air nozzles together with the electric eye assemblies are positioned in alignment with the central portions of the passageways 75.

Each photoelectric cell 97 is connected by means of conductors 107 to an electronic trigger mechanism 107 shown diagrammatically in Fig. 4 and shown schematically in Fig. 9. The trigger mechanism in turn connects with each solenoid 108 by conductors 107a to a solenoid 108 which is mounted upon each valve 105, the arrangement being such that actuation of the solenoids function to open the respective valve associated with the actuated solenoid. As will be hereinafter more fully described an electrical circuit is so devised that as biscuits are carried forwardly on the conveyor 13 the first biscuit in line traverses substantially the entire width of the machine, intercepting the various light beams of the electric eye assemblies 89. The arrangement is such that the'only photoelectric cell 97 actuated at the initial period of operation is the one most remote from the entrance of the biscuits to the conveyor belt 13. The first biscuit, therefore, intercepts the various light beams but does not function to actuate any of the solenoids 108 until the last beam in the line of electric eye assemblies 89 is intercepted. At this period the photoelectric cell 97 of the last electric eye assembly functions to actuate the solenoid associated therewith and the respective valve 105 is opened to permit a blast of air to issue from the respective nozzle 103. The blast of air is of sufficient intensity to blow the biscuit 3 transversely from the conveyor belt 13. In this fashion the biscuit is blown into the last passageway 75. By the provision of the cover 75' and spring leaf 75a the biscuit is prevented from being blown out of the passageway 75.

The electric circuit arrangement then functions to actuate the next adjacent electric eye assembly so that when the next biscuit in series traveling upon the conveyor 13 intercepts the beam of the actuated electric eye assembly it is similarly blown into the next adjacent passageway 75. This operation is continued until a biscuit has been blown into each of the passageways 75. The electric circult is so devised that when the electric eye assembly for blowing a biscuit into the last passageway, that'is, the first passageway closest to the entrance of the biscuits has been actuated, the next biscuit in line intercepts the beam of the electric eye assembly 101 which at that pe-- riod is actuated. By so intercepting the beam of this assembly, all of the remaining electric eye assemblies are deactuated except the last one in line.

beam of the last electric eye assembly is intercepted at which time the operation is repeated.

Referring particularly to Figs. 1 and 2, an angle iron 109 is transversely disposed acrossthe machine, being supported by opposite blocks 110 carried upon the upper portions of the opposite beams 34. The transversely disposed angle iron 109 is space-d from the angle iron 79 which supports the partition plates 76. Spaced from the angle iron 109 in the direction of travel of the screen conveyor 47 is a second angle iron 11 1 which transversely spans the machine and is supported at its opposite ends by blocks 112 which, in turn, are carried upon the upper portions of the beams 34-34. The angle iron 111 is disposed substantially at the termination of the forward pass of the conveyor 47.

It will be noted that both transverse angle irons 109 and 111 are positioned above the path of travel of the upper pass of the conveyor 47, said angle. irons being adapted to support a plurality of partitions 113, the partitions being disposed substantially vertically and suspended from the angle irons 109 and 111. The partitions 113 are of three forms. The outer partitions 113, designated 114, are of single ply construction, both outer partitions converging inwardly toward the center of the machine in the direction of travel of the conveyor 47. Another form of partition comprises the group of partitions indicated by the numeral 115 which is of double ply construction throughout its entire length, the plies being spaced from each other throughout the length of the partitions. The third form of partition 113 is designated by the numeral 116 and comprises double ply construction for a portion of their length and single ply construe tion for the remaining portion of their length. it will be noted (Fig. 1) that included between adacent double ply partitions 115 are two spaced partitions 116 and included between the outer single partitions 11eand the adjacent double partitions two spaced partitions 116 are included. The arrangement is such that a plurality of adjacent passageways 117 are provided above the surface of the conveyor 47, the passageways 117 being grouped in threes, the double partitions 113 dividing each group of three passageways from the next group of three passageways.

1f the present machine is to be used with a packaging machine which may pack five tiers of biscuits three to a tier within a carton the passageways 117 will be grouped in five groups of three each. In eifect, the number of groups of passageways correspond to the number of tiers to be inserted in the box and the number of passageways in a group correspond to the number of biscuits constituting each tier.

As has been hereinbefore described the biscuits carried upon the conveyor 13 are displaced from the upper pass of said conveyor by blasts from the air nozzles 103.

The biscuits thus displaced are blown into the passageways 75. The biscuits thereupon slide downwardly upon the ramp 73 and are carried forwardly by the conveyor 47. It will be noted that the partition plates 76 are inclined with respect to the direction of travel of the conveyor 47. Hence, as the biscuits are carried forwardly Consequently the biscuit which has triggered the electric eye assembly 1 01 continues its passage upon the conveyor 13 until the Y 7 122 in eflect'being resilient cantilevers.

I j

Referring particularly 't'o-Figs. Z a'nd S, a resilient plate 118 is carried adjacent the end of each partition;

For example, with 1 plate 76 said plate at one e'ndb'eing secured to the end of the partition plate as atfll9, preferably by :Welding,

and the'oppo'site end being 'spacedfrom therespective par-. 7

tition .plate' 76 by the spacer clamp 12$. The ends-of'each plate fllsadjacent the clamp 1 20 is not secured to said clamp, but is free to 'move inwardly towardthe partition 76 upon which its opposite end is mounted. Each'plate: 1118 thereby normally assumes a bridging position with 7 respect to corners 12I'where'the partition plates are bent from their inclined position to a parallel. position with respectfto the direction of travel of the conveyor 47. A

v resilient tongue122 is struck up from each plate 118 and extends'inwardly into each passageway 77, the tongues Theends of the partition plates 76 are spaced from the ends of the partitions 113- in thedirection of travel 7 i of theconveyor 47. The ends of said'partition plates and partitions are additionally offset laterally flwith respect to i a each other so that the transverse distance from 'theiactive face a of partitioniplate 76 to the leading corner of partition' 113 is'less/than thelongitudinal, but greater than the transverse dimension of the biscuit, The at rest or normal position of 'each resilient plate. 118 and resilient tongue 122 is 'suchthat' no contact with the biscuit is made by either of these elements if the biscuit is disposed with its longitudinal dimension. parallel to partition -pla'te'76.'f Q W r 1 The arrangement issuch'that a biscuit 3 which may move through a predetermined passageway 77 arrives adjacent'the .end 123; of plate 118 in one ofthreeposi;

The result 7 of @this'positioning' is illustrated in Fig. 7 by biscuit 123.

As the biscuit moves forwardly fronithe end of plate 76, the" corner"139 of] biscuit" 125 contacts the 7 corner of t the partition 113, thus rotating the biscuit 128; in a clock wise dire'ctiona'nd ali ningits longitudinal airisiparallel 'withpartition'llza. 3 V V rotation from the posit on re- L c C. in counterclockwise ferredito inB above. if the-biscuitinitially deposited in B above, it is more or lessunstable relativeto rotation about" a vertical axis," since by virtue'fof 'thecincli nation of the partition plates 76- the biscuittends to slide along the face a of the partition 'plate and'to this cX- tent this end of the biscuit is retarded relative to its oppo site end.

Continued motion of the" i a biscuit along line 126 induces a clockwise rotationto align the biscuitlZS with its longitudinal axis at" substantially right angles' to the partition .plate 76.
